I did the first oil change a little early to make sure there was no extra material (as microscopic as it may be) floating around in the oil since it was a new engine. Looking back, I probably would have done it differently since I'm a little overboard with protecting the mechanicals:
1,000 miles - change oil filter only
2,000 miles - change oil filter only
3,000 miles - change oil filter and oil - check drain plug for "extra material" captured
From that point out, I'd continue with my regular maintenance schedule, which is:
Oil Life = 65% - change oil filter only
Oil Life = 30% - change oil filter and oil - reset oil life indicator
Since I have an aftermarket tune and drive a little more aggressive from time to time, I'd rather not go below 30%. But, that's just me and my $0.02.

It's not as often as it seems. Changing an oil filter is a $5 ordeal and I'd rather be safe than sorry in the long run. Basically, I get about 6K~7K miles out of an oil change and 3K~3.5K out of each oil filter. Since they put 'em up on top of the engine, they're real easy to change.

Based on my previous research with engine oils, Mobil 1 5W-30 is generally good for 7500-9000 miles based on used oil analysis and the TBN. Above this range, the oil becomes really thin, the TBN drops sharply, and the oil isn't of any use.
How does GM's oil life indicator compare with the used oil analysis?
Based on my annual mileage, I just change the synthetic oil and the filter once a year. BMW/Audi specify 10,000 mile oil change intervals (no month or time limit is specified).

does that DIC thing take into account other brands of oil, like will it not read oil life correctly if i put in amsoil instead of mobil 1 and how does that oil life thing work anyway, what does it do, measure viscosity or something, amazing

Engine Oil Life System
When to Change Engine Oil
This vehicle has the Engine Oil Life System, a computer
system that indicates when to change the engine oil
and filter. This is based on engine revolutions and
engine temperature, and not on mileage. Based on
driving conditions, the mileage at which an oil change is
indicated can vary considerably. For the oil life system
to work properly, the system must be reset every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE OIL SOON message comes on. See DIC
Warnings and Messages on page 3-46. Change
the oil as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the best
conditions, the oil life system might not indicate that
an oil change is necessary for over a year. However,
the engine oil and filter must be changed at least
once a year and at this time the system must be reset.
Your dealer/retailer has trained service people who
will perform this work using genuine parts and reset the
system. It is also important to check the oil regularly
and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 3,000 miles (5 000 km) since the last oil
change. Remember to reset the oil life system whenever
the oil is changed.

So in other words, if you use your car like a normal person, the oil life indicator should give comparable results based on mileage. The major differences come into play when you use your car abnormally:
Idling for long periods of time (police cars)
Operating at high RPMs for long periods of time (hot laps at Nordschleife)

+1 I usually change at around 55%.
I just saw in your signature that you blew your turbo... what happened? Do you think it was because of the tune? Did you get it fixed under warranty or did they give you a hard time?
